480 CORK INSULATION because it will be washed off. It must be given time to set. With sunshine it will dry in two to three hours. A man will soon learn i.. give 350 to 400 square feet surface per hour one coat. The quantity of the various materials required per 100 square feet of surface may be obtained from the manufacturers. The following data were obtained from the Lewis Asphalt Engineering Corp.: Karnak Korkphalt 70 lb. per layer of corkboard Korkseal (or Krodeproof), first coat 4 gal. Korkseal Mortar (finish coat) 5 gal. Korkseal Enamel, white, per coat Ys gal. Korkseal Aluminum, per coat % gal. Strength.—Tests have been made for the United <strong>Cork</strong> Companies, New York, to determine the tenacity of adhesion of a 3-in. thick slab of corkboard cemented to concrete. When a pull was exerted of 1,360 pounds per square foot cork, the cork yielded, but not the asphalt emulsion, which proves conclusively that the emulsified asphalt furnishes a very reliable bond. In fact, the adhesive strength of Par-Lock asphalt alone was found by the Investigating Committee of Architects and Engineers, New York, to exceed 125 pounds per square inch, equivalent to 18,000 pounds per square foot. Its ductility is rated at four to five centimeters at 77° F. The penetra- tion of a needle bearing a 200 gram weight is twenty-five to thirty millimeters per minute at 77° F. The re-melting point of these surfac- ing asphalts is between 200° and 215° F. when tested by Bureau of Standards ring and ball method. The re-melting point of the hot asphalt used for dipping one face and two edges of corkboard should be between 180° and 200° F. It should be heated to the consistency of molasses, the slabs firmly pressed against the surface asphalt, such as Krodeproof, until the asphalt in the joints chills. Mastic Asphalt Facing.—The Korkseal or asphalt mastic finish, J/^-in. thick, above described, is an improvement over the method of ironing on the asphalt plaster at the factory to each slab of cork, because the subsequent patching up of the many lineal feet of joint is a difficult and expensive task, and the result is not equal in air and water tightness to that of a continuous troweled facing. Not to chip off readily, a tough grade of asphalt is used which is hard on the saw when fitting slabs into place. This asphalt becomes very brittle at low temperature. It has to be a hard variety so as not to run during shipping in summer. Some <strong>insulation</strong> manufacturers do not urge the use of the Korkseal asphalt plaster where the cork is exposed to injury from the handling of goods. There they recommend again the old Portland cement plaster finish, at least J^-in. thick; but even here the advantage of moisture proofing should not be sacrificed. One can erect suitable fenders, rails and baseboards to prevent truck wheels from damaging
FIRE RETARDANT 481 the wall, or one can provide a cement wainscoat 54-in- thick over the asphalt dampproof emulsion. Detailed instructions for waterproofing and dampproofing in building construction are contained in circulars issued by manufacturers. Asphalt emulsion, like Korkseal, is also effective for sealing pipe coverings and is greatly to be preferred to the black crude oil paint or tar commonly employed for this purpose. HOW INSULATION SAVED A REFINERY.* An interesting example of how material installed for one purpose may render valuable service in a quite unexpected way occurred last summer at the plant of the Island Petroleum Co., Neville Island, Pittsburgh, Pa. The company had recently <strong>complete</strong>d three steel cold settling tanks, 20 feet in diameter by 25 feet high, for bright stock. Being operated part of the time at low temperature produced by brine refrigeration, these tanks were insulated with three inches of Nonpareil corkboard furnished and installed by the Armstrong <strong>Cork</strong> & Insulation Co. At the time of this incident they were practically filled with oil. On August 25, 1921, during a violent electrical storm accompanied by unusually heavy rain, lightning struck one of the crude oil tanks. The resulting explosion released a large quantity of burning oil which spread out over the partially flooded yard and practically surrounded the nearest settling tank; hastily constructed dikes shut it off from immediate contact with the others. For nearly three hours the fire raged around this tank, and for almost an hour, the flames were leaping directly against its sides, while the officials and employees, striving to stop the spread of the fire, momentarily expected the big tank to "let go" with consequent disaster to the entire plant. Three times the hatch on the roof lifted to allow the escape of accumulated gas, but the remarkable heat retarding quality of the corkboard <strong>insulation</strong> kept the temperature below the danger point, and the fire finally burned itself out with no further loss of property or damage to the insulated tank beyond a slight charring of the outer surface of the corkboard <strong>insulation</strong>. The Island Petroleum Co. officials are unanimous in the opinion that nothing but the protection afforded by the <strong>insulation</strong> prevented the destruction of all three tanks and the heavy loss such an explosion would have entailed. Though <strong>insulation</strong> may seldom be called upon to withstand so severe a test, the record of this performance is convincing proof of the nonconducting property and fire resistance of corkboard. *Extracted from Ice and Refriyeratwn, June, 1922, Page 460.
